Holley blue pump, and a Holley reg will be fine for 280 to 300 BHP (engine)
If no holley blue then two Facet pumps (not in series!) will do the job.
Fuel pressure of around 4.5psi or even 6psi (depending on the type of needle and seat valve you have in the carb will be sufficient, Also you will need to put in 1/2 inch line from the tank to the pump to the carb to get the fuel flow you require without using higher fuel pressure than mentioned.

That is a Factory PP too 
I miss my n/a PP sooooo much.................
The "barking" noise through the carb at idle and under acceleration is just unbelievable, much more intense than any bridge or J port.
Bit extreme for the street though, I had mine as a daily driver for 4 years ! Ah the good old days.

Not me!
Still having fun with them!
I had one on the dyno this past weekend. The concrete floor in the Dyno room was vibrating just like when those Top Fuel/Nitromethane drag cars do when they run down the strip!
The sound at 10,000 rpm is sweet!
Weber carbs are the best too! There aren't any other carb you can tune like a fine piece of musical instrument!
Like someone said before--->
Rotary Engine=The most efficient way to turn fuel into noise!
